	<H1>PERT Help</H1>
	<HR>
	PERT provides tools, handles, and commands to manipulate a PERT
	diagram.
	<P>A task is shown as a box with a line for the task's name, a line
		for the task's duration, and a line for the task's earliest end time.
		Only the task's name and its duration are editable. The end time is
		calculated automatically by PERT.
	<P>Circular dependencies are shown in red.
	<P>
	<H3>Tools</H3>
	The tool palette on the left offers several tools that either create
	new figures or manipulate existing ones.
	<Table Border=0>
		<TR>
			<TD><img src="../../images/SEL1.gif">
			<TD>selects, moves or resizes a figure; the shift-key toggles
				the selection. Dragging the selection tool in the background selects
				the figures within the dragged rectangle.
		<TR>
			<TD><img src="../../images/PERT1.gif">
			<TD>creates a new task
		</TR>
		<TR>
			<TD><img src="../../images/TEXT1.gif">
			<TD>creates a new or edits an existing text figure
		</TR>
		<TR>
			<TD><img src="../../images/CONN1.gif">
			<TD>creates or adjusts connections between figures. A connection
				is split into segments by dragging a point on the connection. To
				join two segments click the end point of a segment

	</Table>


	<H3>Handles</H3>
	When selected figures offer different handles to manipulate them.
	<ul>
		<li>the blue circle handle is a connection handle. It allows to
			create connections between figures.
		<li>the framed red handles are null handles. They only show the
			selection status of a figure but don't support any manipulation.
		<li>the green handles are shown on connections. They enable to
			reconnect them with another figure.
		<li>the yellow handle enables to change the font size of a text
			figure or the size of the radius of a rounded rectangle.
	</ul>

	<H3>Commands</H3>
	Commands are invoked from the button bar at the bottom (applet) or from
	the menu bar at the top (application).
	<P>The standard commands that are provided include, cut, copy,
		paste, duplicate, delete, group, ungroup, bring to front, and send to
		back.
	<P>
	<H3>Attributes</H3>
	Attributes, such as fill color, text color or arrow tip, can be changed
	through the attributes menu (stand-alone) or the pop up menues
	(applet).
